Combining exercise and medication to reduce bone loss during weight loss in older adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This research aims to identify effective strategies to minimize bone loss in older adults undergoing weight loss. Participants will engage in a 12-month intervention that includes resistance training, bone-loading exercises, and bisphosphonate treatment, while all receiving a group-mediated dietary weight loss program. The study will assess changes in bone mineral density and quality through various imaging techniques over a period of up to two years. Participants will be randomized into one of four groups to evaluate the independent and combined effects of the interventions.
